ROLL-HOLDER FOR PRINTING-PRESSES.

Specification of Letters Patent.

- Patented July as, 190s.

To all whom 'it may concern:

Be it known that I, HANS P. HUSBY, a citizen of the United States,'residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Roll-Holders forPrinting- Presses, of which the following is a specification, referencebeinghad to the accompanying drawings.

My invention relates to roll-holders for holding a roll or web of paperas commonly used in perfecting presses, and it has for its .object toprovide a new and. improved rollholder by which the roll may be quicklyand iirml secured upon the shaft or mandrel by whic it is supportedwhile on the press; also to provide a construction by which therollholder may readily accommodate itself to diameters. f I accomplishthese objects as illustrated lin the drawings and as hereinafterdescribed; i

That which I believe to be new is set forth in the claims.

In the accompanying drawings,-Figure 1 is a sectional view of a roll,showing my improved roll-holder; 2 is a partial longitudinal'sectionofthe roll-holder; Fig. 3 is a v similar view, showing the parts inlocking position; Fig. 4 is a cross-section on line 4--4` of Fig. 2;Fig. 5 is a perspective view of a part of the clamping,mechanism; Fig. 6is a perspective view of one of the blocks by which the shaftis'clamped; Fig. 7 is a perspective view of one .of "the rocking leverswhich eng-age the clamping blocks; and Fig. 8 is a sectional view,showing a modification.

As is well understood in the art, and as illustrated in Fig. 1, a web ofpaper is usually wound in a roll upon a hollow tube or core,-- 10indicating the web and 11 the core.

l2 indicates the usual shaft or mandrel, which in practice is passedthrough the tube 11 and is tted in suitable bearings on the pressso thatthe web may unwind freely as the paper is consumed.

13 indicates a normally stationary head, which is secured upon one endportion of the shaft 12, preferably by a set-screw 14, so that vide`ried by a frame or support 26 which iits upon 4.

conical portion 15 of the head 13,-the ar- A rangementJ being such thatby movin vthe head 16 toward the head 13 theroll tu e 11 may bewedged-tightly between said blocks. The head 16 is provided with/asleeve 18, the inner portion of which is externally screwthreaded, asshown-at 19 in Figs. 3 and 5,- the outer-end portion being providedlwith longitudinal slots or recesses 20 at suitable intervals, as shownlin Fig. 5. Said slots are open at their outer ends to permit of theparts being assembled.

Itl will be understood that the sleeve 18 iits loosely upon the shaft 12so that it may be rotated or moved longitudinally there-v with a' upon.Said sleeve.is also provide shorter slot 21 closed at its ends for apurpose which will hereinafter appear.

22 indicates a series of clamping blocks or keys, theinner faces ofwhich are corrugated, as shown at 23 in Fig. 6, and which are adapted toiit in the slots 20 in the sleeve 18. By pressing the blocks 22 inwardagainst the shaft 12 they may be caused to bite the same with sufficientforce to prevent the rotation or longitudinal movement of the sleeve 18u on the shaft. For actuating the clam ing b ocks 22 rocking levers 2 4are pro- Which are mounted on pivots'25 carthe sleeve 18, as shcwninFigs. 2,v 3, an In the principal iigures I have shown the support 26 asbeing arranged'to support vfour levers 24,-the sleeve in this case eingproyided with four slots 20, with a corresponding number of clampingblocks22. In Fig. 8 I have shown'a correspondingframe 26, designed toaccommodate three of said levers 24, the arts being in other respectsthe same. (l) levers and clamping blocks may be employed.1

'lhe levers 24 are bell-crank levers, each having an inwardly-projectingarm 27 which iits in a suitable recess in the adjacent clamping block22, as shown in Fig. 3*thus not y insuring the proper engagementvbetween said arm and the clamping block but also providing for movingthe clampin blocks longitudinally of the shaft 12' with bviou'sly, anydesired' number ofv .A said levers when desired.- The levers 24 are alsoprovided with horizontally-extending arms 28, which project over a Wede-block 29 mounted upon the screw-threa ed por--4 tion ofthe sleeve 18,as shown in Figs. 2 and 3. Itwill be observed that the wedge-block 29li'es between the head '16 and the levers 24,

, so that by rotating saidwedge-block upon 18-16, and as said heads arelocked to the,

' shaft 12 the roll is also secured to said shaft.

By rotating the wedge-block 29 in the oppo site direction, the shaft- 12is released and the clamping mechanism may be readil movedlongitudinally thereof to at once re ease the roll. To prevent excessivemovement of the frame 26 upon the sleeve 18 I rovide a setscrew 30 whichpasses throug said frame and into the slot 21 in said sleeve, as shownin Figs. 3 and 4; The screw 30 is removed when the parts are to be takenapart.

have thus provided a clamp which is readily adjustable to engage ordisengage the roll,

and which may accommodate itself to roll tubes of diiferent'lengths ordiameters; also one which may readily be removed from the shaft withoutbeing disassembled, and which may be locked to the shaft at any pointthat may be necessary to accommodate the roll prisin mounted thereon. Y

While I have described in detail the embodiment of my inventionillustrated in the accompanyingdrawings, I wish it to be understood thatmy.invention is not restricted to the details of theconstructiondescribed, except in so far as they are specificallyclaimed, but includes generically the subjectmatter of the broaderclaims.
